SPECIFICATION forming part of Letters Patent No. 418,048, dated December 24, 1889.

Application filed April 24, 1889. Serial No.,308,407. (No model.)

.To all whom it may concern:

Beit known that I, THOMAS M. MURPHY, ofSt. Louis, in lthe State of Missouri, have invented certain new and useful Improvements in Sprinklers; and I do hereby'declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying-drawings, in whichn Figure l shows a vertical central section of my sprinkler with the valve closed, so as to shutoff the water" from the sprinkling-slot,

Fig. 2, a similar view with the section plane,

at right angles to the plane of section in Fig. I and the parts in position as when sprinkling is being done, and Fig. 3 a perspective view of the various parts of the sprinkler separated from each other.

Letters of like name and kind refer to like parts in each of thegures.

The object of my invention is to provide an improved sprinkler; and to this end myv for other purposes than sprinkling streets.

Such nozzle, as is fully set forth in said patent, has, instead of a series of. openings or holes for the exit of small streams 0f water, a narrow slot in combination with a distributing or spreading lip extending upwardly and outwardly from the lower sideof the slot. As explained at length in the specification of the patent, the lip is continued around beyondthe ends of the slot, while the slot itself is of one shape when the nozzle is to be used alone and of another where a pair of nozzles are employed, each to sprinkle one-half of a space; This combination of slot and lip I employ in my present nozzle with the same which can be easily and readily adjusted at will from the seat of the sprinkling-cart or elsewhere, so as to throw athinner or thicker sheet of water to wet down a surface less or more, as desired. Vith this object in view I have done away with the adj usting-sleeve with fastening set-screws used in my patented nozzle and have provided the adjusting or regulating means to be described hereinafter.

In the drawings, A designates a tubular casing of brass or any other desired metal or material. As shown, such casing is cylindrical in general shape, but I do not limit myself to that form. At one side of it is a threaded opening A for receiving thc supplypipe or a coupling on the latter.

On the upper end of casing A and fastened to it, preferably, by being screwed into it, as

shown, is the cap A2, having the upwardlyextending hollow neck A3, Whose interior, cylindrical in shape, is of less diameter than that of the casing. The upper end of this neck is provided with a central opening for a purissue-slot C and distributing-lip C, constructed and relatively arranged as in my patented nozzle hereinbefore referred to. The walls of piece C are made of such thickness that their inner face is substantially iiush with that of the upper unrecessed or uncutaway portion of piece B. While the -lip O2 can be made in one piece with piece 0,1 prefer to form it, as shown, upon a separate plate C3, which is fastened to piece C, so as to constitute the bottom thereof. The lower side of issue-slot C is then formed by the plate. Piece C is guided in its up-and-down movements within the piece B by screws b b, tapped through the sides of piece B and engaging vertical slots c c .in piece O. The length of these slots is such as to allow sufficient up-and-down movement of piece G to IOO cause the issue-slot C to be entirely covered or uncovered by the lower edge of piece B, as indicated in dotted and full lines in Fig. 1. The adjustment of the piece C up or down between the limits of its movement will cause more o r less of the slot to be covered or closed by the piece B, so that the sheet of water which can issue will be thinner or thicker.

As the piece C should be capable of easy up-and-down movement, I do not attempt to make it lit so closely within piece B as to prevent all chance of leakage, but cover the` joint or space between its upper edge and the annular shoulder at the top of the recess or enlargement within piece B by means of a dependent annular lip D, extending down from the upper portion of piece B in contact with the inner face ot piece C. Such lip can be formed upon or integral with piece B; but I prefer to make it separately in the form of a cylinder and attach it to the inner face of piece B, as shown in the drawings. While it can be made of metal, I prefer to make it of rubber or leather, so that it will be lieXible and can be forced outward against the inner face of piece C by the pressure of the Water flowing through the nozzle.

For fastening` the rubber lip or cylinder in place I use the clamping-ring D', held against the inner face of the cylinder so as to clamp the upper edge of the latter between it and the piece B by means of screws d CZ and nuts d d.

In the bottom of the slot and lip carrying lower part C, forming the nozzle proper, is a central opening E,V down through which eX- tends the threaded end of a tube F, whose upper end is provided with an angular or rect-angular shaped opening F. The interior of the tube below such opening is made cylindrical and of a diameter equal to or greater than the greatest diameter of the opening. An annular shoulder F2 on the tube near its lower end engages the upper side of the plate C3, forming the bottom of piece C, while a nut F3, screwed upon the projecting end of the tube, engages thel lower side of the plate around the opening E. Viththis nut screwed up in place the plate around the edge of such opening will be clamped between the nut and shoulder F2, so as to fasten the tube firmly 'and rigidly to plate C3.

Upon a stem or rod G, arranged centrally within the nozzle, is avalve disk or head G, adapted to rest when down upon a valve-seat ,G2 on the upper end of piece B, so as to close the passage from casing A downward to the slotted portion of the nozzle. This Valvehead, which canbe formed or fixed on the rod in any desired way, is preferably provvided with a rubber or leather facing G3 to engage the valve-seat and make a tight joint `when the valve is down. The portion ot' the valve rod or stem above the valve is made cylindrical and extends up through the central opening in the top of the neck A2 of cap A2. Upon the rod within such neck is a head G4, adapted to fit closely the interior of the neck. Such head is provided with a packing G5, preferably of rubber, but of leather or other semi-elastic material, if desired, which, engaging theinner face of the neck,effectually prevents any leakage of water up around the stem through the stein-receiving opening at the top of the neck. The lower portion of the stem or rod G is made angular in shape,

so as to fit and be capable of sliding through the opening F in the tube F, fixed to the bottom of the lower slotted portion C of the nozzle.

YUpon the extreme lower end of the rod is secured the nut H, cylindrical in shape and of such diameter that it projects beyond the fiat sides of the rod. Vith this construction the upper end of the nut forms ashoulder to strike the under side of the top of tube F when the rod or stem G is raised, as shown in Fig. 2. For securing this nut in place and preventing ils working olf I provide a nutlock consisting of a pin II', extending through the nut and the threaded portion of the rod upon which the nut is screwed.

The distance from the valve-head G to the upper end of the nut is such that when such head is down, as shown, so as to rest upon its Valve-seat to close the passage to the sprink' ling-slot, and the lower portion C of the nozzle is down in its lowest position, all as shown in Fig. l, the nut H will standv at some distance below the upper end of the tube F. With the parts in this position the head G4 on the stem or rod stands within the lower end of bonnet or cap A2. The water entering the casing Ais now confined to such casing by heads G G4, so that it cannot liow down into the parts B and C of the casing or up within the cap or bonnet A2. If, now, itis desired to set the nozzle in operation, the stem or rod G is drawn upward, so as to raise the Valve G and let the water down within parts B and C to issue from the slot C. The position of the nut H on the stem with reference to the upper end of the tube F allows the stem yto be raised far enough to openwide the valve before the nut strikes the tube end. The valve is then opened to admit free iiow of water down through the nozzle, and the piece C is down, so that its slotc is entirely uncovered by the lower edge of part B. rlhe sheet of water issuing from the slot and pass- IOO IIO

ing upward and outward over the lip is then v of the greatest thickness possible with the nozzle. It it be desired to make the sheet or stream thinner, so as to wet down a space less, as where an asphalt instead of a granite or a macadam pavement is to be sprinkled, the stem or rod G is drawn up farther by any desired means, as by a lever worked by the driver of the cart from his seat. The engagement of the nut H with the upper end of the tube F then causes, as the rod G rises, araising or lifting of the slotted nozzle with reference to the piece B, so that some of the upper which the stream or sheet of water can pass is made of less height.

The casing A and bonnet or cap A2 are made of such length as to allow the heads G and G4 to move upward with the rod until the latter has raised the piece C to bring the issue-slotof the latter entirely within the lower end of piece B. The sheet or stream of water can thus be adjusted to any desired thickness by the upward movement of the rod G after the valve has been opened. As the piece C is raised, the lip C2 at the lower side of the issue-slot C is brought nearer and nearer the lower edge of piece B, so as to conline the stream or sheet of water more and more. In order to allow the most free upward and outward iiow of the water from the slot over the distributing-lip, the edge of piece B is on its outer side rounded or inclined upward and outward, as shown in Fig. l. If during a sprinkling operation itis desired to shut off the sheet of water, as in passing an obstructionor through a narrow place, the rod G can be quickly raised to lift piece C, so that the edge of piece B will entirely close the slot C. Upon lowering the rod again the piece C can be allowed to drop again to the proper position i'or causing the delivery of a sheet or stream of the desired thickness. Then the sprinkling operation is completed, the rod can be allowed to drop orbe forced down to its lowest position, so that the valve G will rest upon its valve-seat to shut oft' the water from the delivery part of the nozzle. The piece C will then drop to its lowest position again, as shown in Fig. l. With the rubber lip or jacket lapping over the space between the upper end of piece C and the shoulder within piece B there can be no leakage of water out around piece C even when the latter its the piece B but loosely.

I do not claim or intend to cover by the claims in this case, broadly, a nozzle made movable within a casing, in combination with means for fastening it as moved, but without means for moving and adjusting it to any desired position with reference to the casing.
